Operating Instructions
1. Remove the Microcentrifuge from the box and examine all of the contents for breakage or miss-
ing parts. Save all packaging and paperwork.
2. Place the Microcentrifuge on a fl at, stable surface. The unit should be placed in a
non-hazardous environment and located near an electrical outlet.
3. With the power switch in the off position, attach the power cord to the back of the
Microcentrifuge and to the grounded electrical outlet.
4. Turn the power switch to the "ON" position. The Microcentrifuge will automatically perform a
safety check on the locking mechanism. Open the lid by pressing the illuminated button located
on the front of the unit.
5. Insert your pre-loaded sample tubes into the rotor. Make sure all tubes are fi lled to equal levels
and the lids are closed. Tubes must be balanced properly.
6. Close the lid and the Microcentrifuge will begin the centrifugation cycle. IMPORTANT
:
If
there are loud / unusual sounds or excessive vibrations discontinue operation immediately.
See the Troubleshooting section in this manual. If you cannot correct the problem, contact
Cole-Parmer for assistance.
DO NOT CONTINUE TO OPERATE!
7. When centrifugation is completed, once again, press the illuminated button on the front of unit to
stop the spin cycle motor and open the lid. Do not open lid until rotor comes to a complete stop!
Remove your samples from the rotor.
8. The Microcentrifuge lid is secured by two locking pins that prevents accidental lid opening during
operation and greater safety for the operator. When the Centrifuge has completed the spin cycle,
an automatic lid unlock will occur. If the lid does not open, press and hold the button on the front
of the unit for one full second, the Centrifuge will unlock the lid again. Should the lid fail to open
by pressing the front button or in the event that the power to the Microcentrifuge is interrupted,
the Microcentrifuge lid can also be opened manually by inserting a fl at head screw driver into the
bottom of the unit and moving the release lever to the right. This will release the pins and allow
the lid to open. See Figure 1, page 6.
9. The Microcentrifuge has been designed with an automatic shut-off feature that discontinues
operation after 60 minutes of continuous use. This will prevent the unit from running
continuously if left unattended.
For proper operation, samples must always be loaded into the rotors in a balanced fashion. The
tubes should be filled to the same level, lids closed and placed opposite each other in the rotor.
Tubes and strips must always be loaded symmetrically.
Rotor Installation and Replacement
The Microcentrifuge features snap on rotors that can be installed and removed without an Allen
wrench. There are no set screws to tighten or loosen.
1. Make sure the Microcentrifuge's On/Off switch is in the "Off" position.
2. Line triangular opening on the rotor with the rotor shaft and press down until the rotor snaps in
place. Pull up on the rotor to remove.
3. Turn the unit back to the "On" position, load tubes per the operating instructions and close the lid
to begin centrifugation.
CAUTION: Spin Balanced Loads Only
CAUTION: Do Not Open Lid Until
Rotor has Completely Stopped
